Transcript for Young Guns: Can You Really Hide Guns From Children?
And next, right here tonight, our special report on children and guns in our homes and at the neighbors' homes, where our children play. Every other day, a child is accidentally shot to death. So, we at ABC news wanted to start a conversation about what we can all do together about making them safe. Earlier, we showed you our little experiment. You tell kids not to touch guns. And you watch what they do when they think no one is watching. We showed stunned parents who told their children never to touch a gun, see what the children do, when they think no one is watching. Don't touch the gun. Reporter: When the words say don't touch it. Tell an adult. Don't touch. I know. Reporter: Their bodies can't seem to resist. They look for bullets by staring right down the barrel of the gun. They re-enact the movies, aiming at each other. They can learn the knowledge. They can sit down. We could ask them to repeat it. But you can't educate you're curiosity out of a child. Reporter: There's another question. Since one in three homes on average has guns in it in American neighborhoods, a lot of parents thinking they've hidden them safely away from young children, tucking them away in the closet. One in a hollowed-out bible. And keep in mind, the NRA recommends that guns be stored so they're not accessible to children. The question is, what is inaccessible to a child? You've seen videos like this one on youtube. Give a child an incentive, and they can do impossible things to get where they want to go. And you'll see parents like Stephanie, who is so sure her 4-year-old son doesn't know she has a gun, much more where she placed it. He takes us to the first place where it had been stored. And when she moves the gun, to a truly secret hiding place, we come back one month later. Anwhguess at? He's found that one, too. It's up there, mom. Reporter: Josh asked for a flashlight to point out that pump-action shotgun. Thanks. Up there. It's up there. I can't reach it. Up there. How did you know it was up there? Why you move it? To keep it safe. You don't want anybody to take this gun? I don't want anyone to touch it. Reporter: Stephanie points out, it is unloaded. But since so many little American children live in homes with guns, or play at their neighbors' with guns, we wondered, how many parents ask the question, what's gun safety in your house? I think the parents will be surprised to see which of their friends actually own guns. Reporter: So, we decide to go knocking. What we find is a big surprise.
